Why do we exist? Just to suffer? Fun game, precise platformer making me appreciate not playing Getting Over It and similar games. I'm a big fan of the level design here. I having multiple routes is great and it's hard enough where I fail, I'm on the next ability, and my impatience pushes me to use that ability in a new way. Alternating horizontal and vertical movement options works nicely for that too. Sometimes I just sit there and wait though, making me wish I had access to the full array of the abilities and the skill check was using the right one fast.
Constructive Criticism: The little guy is super silly, but I'm sure you knew that already. I didn't realize the cannisters/tubes were checkpoints, so I missed them at the start. Also, the amount of stress falling from high up and trying not to hit a checkpoint on the way down is incredible, and I'm not sure if that was a deliberate design choice because most times you place lava right under so it comes off as frustrating (sequential can't go back checkpoints maybe?). Controls are a bit floaty, I think it would dramatically improve the feel if they were as precise as the platforming. The last thing is that these types of platformers thrive on recognizable parts of the level, and each zone feels same-y here. Well done!
Bug: I think there's a checkpoint in the air somewhere near the start. When I fell, I panicked and got stuck looping into the lava and stopped there.
